Copper does not react with hydrochloric acid. @IvanNeretin Indeed, but this takes a loooong time before the reaction is noticeable, at least with the acid concentrations I've used for this (several days.) The reaction taking place is reversible. It may be wise to check (using pH or litmus paper) that no acid remains. read more. Zinc. Acids react with metals, bases and carbonates to produce salts. But metal oxides are basic substances, and so they generally react with acids forming respective salt and water. Copper usually does not react with most cold dilute acids. In both reactions one of the products is copper chloride. How do airplanes maintain separation over large bodies of water? Use MathJax to format equations. Hydrochloric acid + copper chloride. When hydrochloric acid is added to a sample of copper why does it look pink at first then form a pale blue solution ? It will take about one week for Cu to react with HCl to form copper chloride CuCl2. All metals do not react with the same rate. Although you should take a look at what Klaus said, copper does in fact react with hydrochloric acid, it just takes a week until all the copper is converted into copper chloride (green) and another week or so until it forms crystals and you can dissolve them in water to form copper chloride again (but depending on the amount of chloride it has, it'll be blue or green).

This is because metals try to replace less reactive cations in single displacement reactions. It is above copper in a metal reactivity series, so copper cannot replace the hydrogen in HCl to form CuCl2. If pure hydrochloric acid is added to a sample of pure copper, there is essentially no reaction; the solution should not turn blue. In HCl there is no oxygen radical to react with copper.
